USING THE DELAY FEATURE

Many agencies use a two-way radio system that might have a pause of
several seconds between a query and a reply.  To avoid missing a reply,
you can program a 2-second delay into any of your scanner's channels or
frequencies.  Then, when the scanner stops on the channel or frequency,
DELAY appears and the scanner continues to monitor the channel/frequency
for 2 seconds after the transmission stops before it resumes scanning or
searching.

You can program a 2-second delay in any of these ways:

  If the scanner is scanning and stops on an active channel, quickly press
  DELAY before it starts to scan again.

  If the desired channel is not selected, manually select the channel
  then press DELAY.

  If the scanner is searching, press DELAY during the search.  DELAY
  appears and the scanner automatically adds a 2-second delay to every
  transmission it stops on.

To turn off delay, press DELAY when DELAY is displayed.


ATTENUATING RECEPTION

To reduce interference or noise caused by signals from a strong local
broadcaster, you can reduce the scanner's sensitivity to signals by
setting the ATT (attenuate) switch on the back of the scanner.  Switch
ATT to 10 dB to reduce the scanner's sensitivity, or to 0 dB to receive
the signal without attenuation.

If you switch ATT to 10 dB, your scanner might not receive weak signals.


LOCKING OUT CHANNELS AND FREQUENCIES

You can scan existing channels or search frequencies faster by locking
out channels or frequencies that have a continuous transmission, such as
a weather channel.  You can lock out as many as 400 channels and 200
frequencies during a search.

To lock out a channel while scanning, press L/OUT when the scanner stops
on the channel.  To lock out a channel manually, select the channel then
press L/OUT until L/OUT appears.

NOTES:  You can delete all the frequencies stored in locked-out channels
        within a bank.

        You can still manually select locked-out channels.

To remove the lockout from a channel, manually select the channel and
press L/OUT until L/OUT disappears.

To lock out a frequency during a band, limit, or direct search, press
L/OUT when the scanner stops on the frequency.  The scanner locks out
the frequency, then continues searching.

NOTES:  The scanner does not store locked-out frequencies during a search.

        If you try to lock out more than 200 frequencies, L-FULL appears.

Follow these steps to remove the lock-out from a frequency.

1.  Press BAND or LIMIT or DIRECT/.to start a search.

2.  Press L/OUT REVIEW.  L-r appears.

3.  Repeatedly press UP ARROW or DOWN ARROW until the frequency you want
    to remove the lockout from appears.

4.  Press L/OUT.  The frequency you want to remove the lockout from
    disappears.

    If there is another locked-out frequency, it appears.  If there are
    no more locked-out frequencies, the scanner continues searching.


Reviewing Locked-Out Channels/Frequencies

To review the channels you locked out, press MANUAL, then repeatedly
press L/OUT REVIEW.  As you press L/OUT REVIEW, the scanner displays
all locked-out channels.

To review the frequencies you locked out, press BAND, LIMIT, or DIRECT/.
to start a search, then press L/OUT REVIEW.  L/OUT REVIEW L/r appears.
As you press UP ARROW or DOWN ARROW, the scanner displays all locked-out
frequencies.


USING THE PRIORITY FEATURE

The priority feature lets you scan channels and still not miss important
or interesting calls on the priority channels.  You can program up to 10
frequencies as the priority channels.  When you turn on the priority
feature, as the scanner scans channels.  It checks one of the priority
channels every 2 seconds for activity.

NOTE:  You can lock out priority channels.  If you lock out all priority
       channels, the scanner displays PCH ALL-OFF when you lock out the
       last channel.

Follow these steps to store frequencies in the priority channels.

1.  Press PROGRAM.

2.  Use the number keys to enter the priority channel number (1-10)
    where you want to store the frequency, then press PRIORITY.

3.  Use the number keys to enter the frequency you want to store into
    that channel.

4.  Press ENTER to store the frequency.

    NOTES:  If you entered an invalid frequency in Step 3, the scanner
            beeps and displays Error.  Simply repeat Steps 3 and 4.

            Your scanner automatically rounds the entered frequency down
            to the closest valid frequency.

            If you enter a frequency that is already stored in another
            channel, the scanner beeps three times and displays the lowest
            channel number where the frequency is already stored, and
            -dUPL- briefly flashes.  Then P and the channel number
            appear and the frequency flashes.  If you want to store the
            frequency anyway, press ENTER again.

5.  Repeat Steps 2-4 to store more frequencies into the priority channels
    (up to 10 channels).

To turn on the priority feature, press PRIORITY when the scanner is in
the scan or manual mode.  Pri -On- appears.  The scanner checks a
priority channel every 2 seconds.  It stays on a priority channel if there
is activity, and P and the priority channel number appear along with the
priority frequency.

To turn off the priority feature, press PRIORITY . P, the priority channel
number, and the frequency disappear.


Locking Out Priority Channels

1.  Press PROGRAM.

2.  Repeatedly press PRIORITY to select the priority channel you want
    to lock out.

3.  Press L/OUT.

    NOTE:  If you have programmed only one priority channel. PCH ALL-OFF
           appears.


CHANGING THE AM/FM RECEIVE MODE

The scanner is preset to the most common AM or FM receive mode for each
frequency range.  The preset modes are:

Frequency Band                   Receive
(MHz)                            Mode

29.0000 - 54.0000                FM
108.0000 - 136.9750              AM
137.0000 - 174.0000              FM
380.0000 - 512.0000              FM
806.0000 - 960.0000              FM

The preset mode is correct in most cases.  However, some amateur radio
broadcasts do not operate in the preset mode.  If you try to listen to a
broadcast when the scanner is not set to the correct receive mode, the
broadcast might sound weak or distorted.

To change the mode, press AM/FM.  AM or FM blinks to indicate that
the displayed receive mode has been changed from the preset mode.

NOTE:  If you change any frequency band's receive mode during a search,
       the scanner no longer uses any of the preset modes.  Instead, the
       scanner uses the selected mode to search for frequencies in all
       bands.

       To return to the default settings, hold down CLEAR, then press
       CLEAR, then press AM/FM.


TURNING THE KEY TONE OFF AND ON

Each time you press any of the scanner's keys, the scanner sounds
a tone.

Follow these steps to turn the scanner's key tone off or back on.

1.  If the scanner is on, turn OFF/VOLUME counterclockwise until it clicks
    to turn it off.

2.  While you hold down 2 and ENTER, turn on the scanner.

3.  After 1 second, release 2 and ENTER.


CONNECTING A DATA LINK TO THE SCANNER

A data interface kit (not supplied) lets you program the scanner with
frequencies stored in a computer.  Contact your local Radio Shack
store for more information.
